Description

【０００１】
【発明の属する技術分野】
本発明は一般にベルト、チェーン、またはコンベヤの構造に関し、特に２つの隣合うベルト、チェーン、またはコンベヤ要素を連結するヒンジピンの望ましくない軸方向の移動を防ぐためのシステムあるいは構成に関する。
【０００２】
【従来の技術及び発明が解決しようとする課題】
すなわち、ベルト、チェーンまたはコンベヤのヒンジピンに加わる軸方向の負荷のため、ヒンジピンが軸方向に移動して、ベルト、チェーンまたはコンベヤの軸方向に隣合う要素との係合が外れるのを防ぐのに、ヒンジピン保持システムが必要になっている。
【０００３】
従来、熱可塑性チェーン及びベルトにおいてヒンジピンを軸方向に移動しないように保持するため、プラグが用いられてきた。こうしたプラグは顎状端部による片持ち式のスナップ嵌合によってチェーンやベルトのリンクに保持されてきた。これらの製品においては、ヒンジピンが顎付の片持ち式アームに引っ張り負荷を加える。
【０００４】
これら従来技術については、以下の各米国特許に注目されたい：

また本発明は、第１のコンベヤ要素と、第２のコンベヤ要素と、ヒンジピンとを備えたコンベヤで、第１のコンベヤ要素が、開口を備え内側に位置した環部と、該内側に位置した環部に隣接且つ離間して両者間にスペースを形成し、該内側に位置した環部の開口と軸方向に位置合わせされ且つ所定の寸法を有する開口を備えた端環部とからなる端部を含み、第２のコンベヤ要素が、前記端環部と前記内側に位置した環部との間のスペース内へと延び、前記端環部と前記内側に位置した環部の各開口に対して軸方向に位置合わせされた開口を備えた環部からなる端部を含み、ヒンジピンが、第１のコンベヤ要素の前記内側に位置した環部の開口及び第２のコンベヤ要素の前記環部の開口を通って延びる円筒状部と、該円筒状部から軸方向に延び、軸方向に沿って外側に拡開した円錐状端部で、前記端環部に隣接して位置する外端を有した対向顎を画成する直径方向且つ軸方向に延びたスロットを備え、通常状態ではヒンジピンが前記端環部の開口を通過できないように前記端環部の開口の寸法より大きい寸法を有する円錐状端部とを含み、通常状態では前記端環部を通ってヒンジピンが軸方向外側へ通過するのを防ぎ、前記顎が相互に接近する方向に変位されたとき、前記端環部の開口をヒンジピンが通過するのを可能とするコンベヤを提供する。
【０００８】
また本発明は、第１のコンベヤ要素と、第２のコンベヤ要素と、ヒンジピンとを備え、第１のコンベヤ要素が、相互に離間しそれぞれの間に一連のスペースを形成している第１連の環部で、相互に位置合わせされ且つ所定の寸法を有する開口をそれぞれ具備する中央部に位置した準一連の環部と、前記中央部に位置した準一連の環部の一端に隣接し、前記中央部に位置した準一連の環部の開口と軸方向に位置合わせされ且つ前記中央部に位置した準一連の環部の開口の直径とほぼ等しい直径を有する開口を具備した端環部とを含む第１連の環部からなる端部を含んでおり、第２のコンベヤ要素が、相互に離間した一連の環部で、第１のコンベヤ要素の環部間のスペース内へと延び、それぞれの間に第１のコンベヤ要素の環部を受け入れる一連のスペースを形成し、相互に且つ前記第１のコンベヤ要素の前記中央部に位置した準一連の環部の開口と軸方向に位置合わせされさらに前記中央部に位置した準一連の環部の開口の寸法とほぼ等しい寸法を有する開口をそれぞれ具備した一連の環部からなる端部を含んでおり、ヒンジピンが、第１のコンベヤ要素の前記中央部に位置した準一連の環部の開口及び第２のコンベヤ要素の環部の開口を通って延び、前記中央部に位置した準一連の環部の開口の寸法よりわずかに小さい寸法を有する円筒状部と、該円筒状部から軸方向に延び、軸方向に沿って外側に拡開した円錐状端部で、第１のコンベヤ要素の前記端環部に隣接して位置する外端を有した対向顎を画成する直径方向且つ軸方向に延びたスロットを備え、通常状態ではヒンジピンが前記端環部の開口を通過できないように前記端環部の開口の寸法より大きい寸法を有し、前記端環部を通ってヒンジピンが軸方向外側へ移動するのを防止する円錐状端部とを含むコンベヤを提供する。
【０００９】
また本発明は、第１のコンベヤ要素と、第２のコンベヤ要素と、ヒンジピンとを備え、第１のコンベヤ要素が、相互に離間しそれぞれの間に一連のスペースを形成している第１連の環部で、相互に位置合わせされ且つ所定の直径を有する開口をそれぞれ具備する中央部に位置した準一連の環部と、前記中央部に位置した準一連の環部の開口と軸方向に位置合わせされ且つ前記所定の直径とほぼ等しい直径を有する開口を備えた内側端環部及び前記中央部に位置した準一連の環部の開口と軸方向に位置合わせされ且つ前記所定の直径とほぼ等しい直径を有する開口を備えた外側端環部を画成する中央スロットを含み、前記中央部に位置した準一連の環部の一端に隣接して位置する第１の端環部と、前記中央部に位置した準一連の環部の開口と軸方向に位置合わせされ且つ前記所定の直径とほぼ等しい直径を有する開口を備えた内側端環部及び前記中央部に位置した準一連の環部の開口と軸方向に位置合わせされ且つ前記所定の直径とほぼ等しい直径を有する開口を具備した外側端環部を画成する中央スロットを備え、前記中央部に位置した準一連の環部の他端に隣接して位置する第２の端環部とを含む第１連の環部からなる端部を含んでおり、第２のコンベヤ要素が、相互に離間した一連の環部で、前記第１及び第２の端環部の中央スロットを占有することなく第１のコンベヤ要素の環部間のスペース内へと延び、それぞれの間に第１のコンベヤ要素の環部を受け入れる一連のスペースを形成し、相互に且つ第１のコンベヤ要素の前記中央部に位置した準一連の環部の開口と軸方向に位置合わせされさらに前記中央部に位置した準一連の環部の開口の直径とほぼ等しい直径を有する開口をそれぞれ具備した一連の環部からなる端部を含んでおり、ヒンジピンが、弾性材料で作製されており、第１のコンベヤ要素の前記中央部に位置した準一連の環部の開口及び第２のコンベヤ要素の環部の開口を通って延び、前記中央部に位置した準一連の環部の開口の直径にほぼ等しいかあるいはそれよりわずかに小さい寸法を有する円筒状部と、該円筒状部の一端から軸方向に延び、軸方向に沿って外側に拡開した第１の円錐状端部で、前記第１の端環部の外側部分に隣接して位置する外端を有した第１の対向顎を画成する直径方向且つ軸方向に延びた第１のスロットを備え、通常状態ではヒンジピンが前記第１の端環部の外側部分の開口を通過できないように前記第１の端環部の外側部分の開口の直径より大きい直径を有し、前記第１の端環部の外側部分の開口を通ってヒンジピンが軸方向外側へ移動するのを防止する第１の円錐状端部と、前記円筒状部の他端から軸方向に延び、軸方向に沿って外側に拡開した第２の円錐状端部で、前記第２の端環部の外側部分に隣接して位置する外端を有した第２の対向顎を画成する直径方向且つ軸方向に延びた第２のスロットを備え、通常状態ではヒンジピンが前記第２の端環部の外側部分の開口を通過できないように前記第２の端環部の外側部分の開口の直径より大きい直径を有し、前記第２の端環部の外側部分の開口を通ってヒンジピンが軸方向外側へ移動するのを防止する第２の円錐状端部とを含んでおり、ヒンジピンの弾性材料が前記顎の相互に接近する方向への移動を可能として、ヒンジピンの両円錐状端部が前記第１及び第２の端環部の外側部分の開口を通過するのを容易にすると共に、前記両コンベヤ要素の開口を通してヒンジピンの組み付けを可能にし、また前記両コンベヤ要素との組み付け状態からヒンジピンを取り外し可能としたコンベヤを提供する。
【００１０】
本発明のその他の各特徴及び利点は、以下の詳細な説明、請求の範囲の記載及び添付の図面を参照することによって当業者には明かとなろう。
【００１１】
【発明の実施の形態】
本発明の一実施例を詳しく説明する前に、本発明の用途は、以下の説明あるいは添付の図面に示す構成部品の構造及び配置の詳細に制限されないことが理解されるべきである。本発明は例示以外の実施例も可能であり、さまざまな方法で実用及び実施化可能である。また、ここで用いる表現と用語は説明を目的としており、制限の意に解されるべきでない。
【００１２】
図１、図２及び図５に、第１及び第２のコンベヤ要素１３と１５及びヒンジピン１７で構成されたコンベヤ、ベルトまたはキャタピラ１１の第１の実施例が示してある。本発明はどんな種類のキャタピラアセンブリまたはコンベヤにも適用可能であり、後で指摘する場合を除き、コンベヤ要素は任意の通常の形態を取ることができ、また任意の適切な材料で作製可能である。
【００１３】
第１のコンベヤ要素１３は熱可塑性材料など任意の適切な実質上剛性の材料で作製可能で、横方向に離間してほぼ直線状に延びた側面２２を具備し、これら両側面２２間に端部２１が位置しており、また相互に離間してそれぞれの間に一連のスペース２５を形成する一連の環部（アイ）２３を備えている。一連の環部２３は、相互に位置合わせされ且つ一定の直径を有する開口または孔２９をそれぞれ備える中央部に位置した準一連の環部２７を含む。
【００１４】
また一連の環部２３は、中央部に位置した準一連の環部２７の一端に隣接し且つ対応する側面２２の内側に位置した第１の端環部３１を具備している（図２参照）。一連の環部２３は、中央部に位置した準一連の環部２７の他端に隣接して位置した第２の端環部４１も具備している。
【００１５】
好ましくは、第１及び第２の端環部３１と４１がそれぞれ中央スロット３５と４５を備え、これら中央スロット３５と４５が中央部に位置した準一連の環部２７の開口２９と軸方向に合致して位置し且つ開口２９の所定直径とほぼ等しい直径を有する開口または孔３７と４７をそれぞれ有した内側端環部３６と４６を画成している。また第１及び第２の端環部３１と４１はそれぞれ外側端環部３８と４８を備えており、外側端環部３８は中央部に位置した準一連の環部２７の開口２９と軸方向に合致して位置し且つ開口２９の所定直径とほぼ等しい直径を有するそれぞれの開口または孔３９を有する。外側端環部４８は盲環部で、孔を備えていない。スロット３５と４５はそれぞれの端環部３１と４１にヒンジピンが存在するか否かの目視による判定を可能とし、またスロット３５は拡開した端部６３を圧縮するようにニードルノーズペンチなど通常のペンチのアクセスを許容し、ヒンジピン１７の取り外しを可能としている。また、ヒンジピン１７に加わる軸方向の負荷が端環部３１の内面に作用した場合、ヒンジピンの端部が拡開するのをスロット６７が可能としている。
【００１６】
第２のコンベヤ要素１５は熱可塑性材料または鋼など任意の適切な実質上剛性の材料で作製可能で、横方向に離間してほぼ直線状に延びた側面５２を具備し、これら両側面５２間に端部５１が延びており、また相互に離間して、第１のコンベヤ要素１３の環部２３間のスペース２５内へと延びた一連の環部（アイ）５３を備えている。一連の環部５３の間隔が、第１のコンベヤ要素１３の中央部に位置した準一連の環部２７を受け入れる一連のスペース５５を画成している。また一連の環部５３は、相互に軸方向に位置合わせされると共に、第１のコンベヤ要素１３の中央部に位置した準一連の環部２７に対しても軸方向に位置合わせされた開口または孔５７をそれぞれ備え、開口または孔５７は中央部に位置した準一連の環部２７の開口２９の直径とほぼ等しい直径を有する。
【００１７】
ヒンジピン１７は熱可塑性材料または鋼など任意の適切な弾性材料で作製可能で、円筒状をなし、第１のコンベヤ要素１３の中央部に位置した準一連の環部２７の開口２９と第２のコンベヤ要素１５の環部５３の開口５７とを貫いて延びると共に、第１のコンベヤ要素１３の中央部に位置した準一連の環部２７の開口２９の直径よりよりわずかに小さい直径を有する円筒状部６１を具備している。
【００１８】
さらにヒンジピン１７は、軸方向に沿って外側に拡開した円錐状の端部６３を具備している。軸方向に沿って外側に拡開した円錐状の端部６３は直径方向で且つ軸方向に延びたスロット６７を備え、スロット６７は中央円筒状部６１内へわずかに延びると共に、第１のコンベヤ要素１３の対応した環部３１に隣接して位置する外端７７と７９をそれぞれ有した対向する顎７１と７３を画成している。端部６３の対向する顎７１と７３は、それらを合わせて見た場合、対応する端環部３１の外側環部３８の開口３９を通り抜けられないように対応する端環部３１の外側環部３８の開口３９の直径より大きい最大寸法あるいは直径を有し、それによりヒンジピン１７が対応する端環部３１の外側環部３８を通って移動するのを防いでいる。
【００１９】
ヒンジピン１７を第１及び第２のコンベヤ要素１３と１５に組み付ける際は、ヒンジピン１７を各環部の該当する開口に通して押し、ヒンジピン１７が適切に位置され、各顎７１の端部が第１のコンベヤ要素１３の端環部３１の外側環部３８から軸方向内側へわずかに離間する状態となるようにする。このように適切に位置されると、各顎７１は自らの弾性作用で通常の離間する位置へと移動し、ヒンジピン１７が端環部３１の外側環部３８を通って軸方向に逆向きに移動するのが防止される。
【００２０】
図３に、第１及び第２のコンベヤ要素１３と１５及びヒンジピン１７で構成されたコンベヤ、ベルトまたはキャタピラ１０１の第２の実施例が示してある。図３に示した構造は、ヒンジピン１７が２部片構造となっており、端環部４８が中心孔４９を備えている点を除き、図２に示した構造と同等である。すなわち、図３に示した構造においては、ヒンジピンの中央円筒状部６１が第１及び第２のサブ円筒状部１０３と１０５に分割されており、これらサブ円筒状部１０３と１０５は一体部片の端部６３と６５からそれぞれ延びている。サブ円筒状部１０５は、溝６９によって相互に分離された一対の顎７３を有する端部を備えている。サブ円筒状部１０３と１０５の各軸方向長さは、所望に応じて配分可能である。好ましくは、サブ円筒状部１０３と１０５の軸方向内側端面１０７と１０９がヒンジピンの軸心に対して直角に延び、シャープな端縁を有している。
【００２１】
図４に、第１及び第２のコンベヤ要素１３と１５及びヒンジピン１７で構成されたコンベヤ、ベルトまたはキャタピラ２０１の第３の実施例が示してある。図４に示した構造は、ヒンジピン１７が３部片構造となっている点を除き、図２に示した構造と同等である。すなわち、図４に示した構造においては、両端部６３と６５がそれぞれ別個の部片であり、また中央円筒状部６１も別個の部片で、鋼から作製可能である。中央円筒状部６１の軸方向長さは、図２に示した構造で用いられている中央円筒状部６１の軸方向長さより短くてよい。各端部６３と６５は、中央円筒状部６１の長さの減少に対応した合計の軸方向長さを有する軸方向内側円筒状延長部２０３と２０５を具備可能である。好ましくは、両端部の円筒状延長部２０３と２０５の軸方向内端及び中央円筒状部６１の両端が面取り部２０７を備えている。
【００２２】
上記の開示した構造の結果として、顎７１と７３がヒンジピン１７の軸方向外側（及び軸方向内側）への移動を防止する。すなわち、ヒンジピン１７をリンクに挿入するとき、対向するそれぞれの顎７１と７３が圧縮され、ヒンジピン１７が完全に挿入されると、顎７１と７３は対応する端環部３１と４１に設けられたスペースもしくはスロット３５と４５内へとそれぞれスナップ拡開し、それによってヒンジピン１７及び対応する端環部３１と４１の対応する外側端環部３８と４８の開口、孔あるいは穴３９、４９間で干渉が生じるようにする。軸方向に負荷が加わると、顎７１と７３が対応する端環部のスペースもしくはスロット３５と４５内でさらに相互に離れるように押されるため、より大きな干渉が生じ、従ってヒンジピンはより確実に保持される。
【００２３】
尚顎７１と７３は、チェーンまたはコンベヤまたはベルトの両側面より内側に位置していることに留意すべきである。この内側干渉が、軸方向の負荷に対してより大きい抵抗を与えると共に、チェーンの横方向側縁の内側すなわちスペースもしくはスロット３５と４５が開放状態であるため、顎７１と７３の機能及び清浄度の検査を可能としている。さらに、開放設計であるからすなわちスペースもしくはスロット３５と４５が存在することから、顎７１と７３を清浄にするのが容易である。
【００２４】
また、上記した開示の構造においては、ヒンジピンの保持が特に汚染を受け易い噛み合い面に依拠してない。

Access to the pliers is allowed, and the hinge pin 17 can be removed. Further, when an axial load applied to the hinge pin 17 acts on the inner surface of the end ring portion 31, the slot 67 allows the end portion of the hinge pin to expand.
[0016]
The second conveyor element 15 can be made of any suitable substantially rigid material, such as a thermoplastic material or steel, and has laterally spaced side surfaces 52 that extend in a generally linear fashion between the side surfaces 52. Ends 51 extend and are spaced apart from each other and include a series of annulus (eyes) 53 extending into a space 25 between the annulus 23 of the first conveyor element 13. The spacing between the series of rings 53 defines a series of spaces 55 that receive a quasi-series of rings 27 located in the center of the first conveyor element 13. The series of ring portions 53 are also axially aligned with each other and are also axially aligned with the quasi-series of ring portions 27 located in the center of the first conveyor element 13. Each of the holes 57 has a diameter approximately equal to the diameter of the opening 29 of the quasi-series of ring portions 27 located in the center.

Opposing jaws 71 and 73 having outer ends 77 and 79, respectively, located adjacent to the corresponding annulus 31 of element 13 are defined. When the jaws 71 and 73 facing the end 63 are viewed together, the outer ring of the corresponding end ring 31 is prevented from passing through the opening 39 of the outer ring 38 of the corresponding end ring 31. It has a maximum dimension or diameter that is greater than the diameter of the 38 openings 39, thereby preventing the hinge pin 17 from moving through the outer ring 38 of the corresponding end ring 31.
[0019]
When assembling the hinge pin 17 to the first and second conveyor elements 13 and 15, the hinge pin 17 is pushed through the corresponding opening in each ring so that the hinge pin 17 is properly positioned and the end of each jaw 71 is The outer ring portion 38 of the end ring portion 31 of one conveyor element 13 is slightly spaced inward in the axial direction. When properly positioned in this manner, each jaw 71 moves to a normal spaced position by its own elastic action, and the hinge pin 17 passes through the outer ring portion 38 of the end ring portion 31 in the opposite axial direction. It is prevented from moving.
[0020]
FIG. 3 shows a second embodiment of a conveyor, belt or caterpillar 101 composed of first and second conveyor elements 13 and 15 and a hinge pin 17. The structure shown in FIG. 3 is the same as the structure shown in FIG. 2 except that the hinge pin 17 has a two-piece structure and the end ring portion 48 has a center hole 49. That is, in the structure shown in FIG. 3, the central cylindrical portion 61 of the hinge pin is divided into the first and second sub-cylindrical portions 103 and 105, and these sub-cylindrical portions 103 and 105 are integrated pieces. Extending from the ends 63 and 65 respectively. The sub-cylindrical portion 105 includes an end portion having a pair of jaws 73 separated from each other by a groove 69. The axial lengths of the sub-cylindrical parts 103 and 105 can be distributed as desired. Preferably, the axially inner end faces 107 and 109 of the sub-cylindrical parts 103 and 105 extend at right angles to the axis of the hinge pin and have sharp edges.
[0021]
FIG. 4 shows a third embodiment of a conveyor, belt or caterpillar 201 composed of first and second conveyor elements 13 and 15 and a hinge pin 17. The structure shown in FIG. 4 is the same as the structure shown in FIG. 2 except that the hinge pin 17 has a three-piece structure. That is, in the structure shown in FIG. 4, both end portions 63 and 65 are separate pieces, and the central cylindrical portion 61 is also a separate piece and can be made of steel. The axial length of the central cylindrical portion 61 may be shorter than the axial length of the central cylindrical portion 61 used in the structure shown in FIG. Each end 63 and 65 can comprise an axially inner cylindrical extension 203 and 205 having a total axial length corresponding to the reduced length of the central cylindrical portion 61. Preferably, the inner ends in the axial direction of the cylindrical extensions 203 and 205 at both ends and the both ends of the central cylindrical portion 61 are provided with chamfered portions 207.
[0022]
As a result of the disclosed structure, the jaws 71 and 73 prevent the hinge pin 17 from moving axially outward (and axially inward). That is, when the hinge pin 17 is inserted into the link, the opposing jaws 71 and 73 are compressed, and when the hinge pin 17 is completely inserted, the jaws 71 and 73 are provided in the corresponding end ring portions 31 and 41. Snap-expand into spaces or slots 35 and 45, respectively, thereby interfering between openings, holes or holes 39, 49 in the corresponding outer end rings 38 and 48 of the hinge pin 17 and corresponding end rings 31 and 41 To occur. When axially loaded, the jaws 71 and 73 are pushed further away from each other in the corresponding end ring spaces or slots 35 and 45, resulting in greater interference and thus holding the hinge pin more securely. Is done.
[0023]
It should be noted that jaws 71 and 73 are located on the inside of the sides of the chain or conveyor or belt. This inner interference provides greater resistance to axial loads and the function and cleanliness of the jaws 71 and 73 because the inner side or space 35 or 45 of the lateral side edge of the chain is open. Inspection is possible. Furthermore, because of the open design, ie, the presence of spaces or slots 35 and 45, it is easy to clean the jaws 71 and 73.
[0024]
Further, in the structure disclosed above, the holding of the hinge pin does not depend on the meshing surface that is particularly susceptible to contamination.
Various features of the invention are set forth in the claims.
